I'd been looking at large camera bags for quite a while, and after looking around the high street, turned my attention to Amazon. I'm so glad I did - I found the Lowepro Slingshot 200 for almost half the price of photographic shops.
I own a Canon EOS 400D SLR, which happily fits in the bag with 3-4 lenses. There's a neat LCD protector for the camera when it's in the bag, and a multitude of pockets for memory cards, cables, filters, pens, etc etc. There's a large seperate compartment at the top for other bits and pieces, like a point and shoot camera.
You're able to access you camera by simply twisting the bag round across your body, without taking it off your back. The main compartment opening of the bag is then the right way up once swivelled so your kit won't fall out.
At the bottom of the bag, there's a pull-out protective cover which protects against rain and dust. If it rains, simply unravel it and stretch across the bag, and your precious kit is safe from the elements.
Overall, the quality is excellent and I was surprised just how many useful little features there are.
All of this coupled with Amazon's sharp pricing and speedy delivery make it a must-have for any camera owner without a proper way to safely transport their gear! 5 Stars.
